In this episode of The Psychology Podcast, Dr. Eric Turkheimer and I take a deep dive into some of the most complex and controversial topics in all of psychology. What is intelligence? How is intelligence measured? Is intelligence meaningful? Is IQ modifiable? Is IQ heritable? What does heritability really mean? Is heritability of IQ the same across social classes? Are there race differences in IQ? If so, what are the potential causes of race differences in IQ? Why does any of this matter? Note to our listeners: This is a very technical discussion, mostly geared towards those who are interested in understanding the debate, and the various nuances on the table. For those who would like to join in the discussion, you can do so below. Enjoy!
